وَحَدَّثَنَا يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ، حَدَّثَنَا خَالِدٌ، - يَعْنِي ابْنَ الْحَارِثِ - حَدَّثَنَا شُعْبَةُ، أَخْبَرَنِي سُلَيْمَانُ، قَالَ سَمِعْتُ مُنْذِرًا، عَنْ مُحَمَّدِ بْنِ عَلِيٍّ، عَنْ عَلِيٍّ، أَنَّهُ قَالَ اسْتَحْيَيْتُ أَنْ أَسْأَلَ، النَّبِيَّ صلى الله عليه وسلم عَنِ الْمَذْىِ مِنْ أَجْلِ فَاطِمَةَ فَأَمَرْتُ الْمِقْدَادَ فَسَأَلَهُ فَقَالَ ‏‏ ‏.‏ "‏ مِنْهُ الْوُضُوءُ ‏"
